Just to give you something to compare to ... I got a 1993 EX Coupe with 72000 miles on it for $6000. It was well taken care of and the only problem I have had is the nice rust that all Civics get near the rear fender. I am also having to put up the brunt of repair parts and such that come with the 100000 mile threshold. If the car has had all of the necessary work done to it (tune up, new clutch, breaks, tires, no rust, alternator, starter, etc) then I say the price is right. If this work has not been done to the car then I wouldn't go higher than $3500, especially for a DX.
